"As you may know, this week has been a challenging one for everyone at Funcom. We initiated a process of reducing costs after the launch of The Secret World and this has naturally affected the production schedule as we work on readjusting the team and our internal development processes," read a statement from the studio.

"As such, we have had to give ourselves a little more time to wrap up Issue #2 and the new release date for this update is September 11, 2012.

"We appreciate your understanding and we apologize for the inconvenience. We are definitely eager to get this update out the door so that you guys can finally get your hands on that awesome rocket launcher."

The 'Issue 2: Digging Deeper' expansion adds new character customisation options through the plastic surgery and barbershop services, additional investigation and action missions, as well as rocket launchers.
